f7c1e5f60d Fix backward compatibility for major:minor query.
Is an application uses query and set major:minor
to device, it should not fallback to default major by default.

Add new function whoich allows that (and use it in lvm2).

436cf94595 Fix readahead calculation problems.
During vgreduce is failed mirror image replaced with error segment,
this segmant type has always area_count == 0.
Current code expects that there is at least one area with device,
patch fixes it by additional check (fixes segfault during vgreduce).

Also do not calculate readahead in every lv_info call, we only need
to cache PV readahead before activation calls which locks memory.

7cd8194c99 Use readahead of underlying device and not default (smaller) one.
When we are stacking LV over device, which has for some reason
increased read_ahead (e.g. MD RAID), the read_ahead hint
for libdevmapper is wrong (it is zero).

If the calculated read_ahead hint is zero, patch uses read_ahead of underlying device
(if first segment is PV) when setting DM_READ_AHEAD_MINIMUM_FLAG.

Because we are using dev-cache, it also store this value to cache for future use
(if several LVs are over one PV, BLKRAGET is called only once for underlying device.)

This should fix all the reamining problems with readahead mismatch reported
for DM over MD configurations (and similar cases).

bb6db55686 Use suspend with flush when device size was changed during table preload.
This allows online mirror resize, also removes condition to preventing
code to do this.

ba856910e0 Add infrastructure for queriying for remote locks.
Current code, when need to ensure that volume is not
active on remote node, it need to try to exclusive
activate volume.

Patch adds simple clvmd command which queries all nodes
for lock for given resource.

The lock type is returned in reply in text.

(But code currently uses CR and EX modes only.)

c94f02648c Merge lv_is_displayable and lv_is_visible.
Displayable and visible is the same thing.

volumes_count(vg) is now vg_visible_lvs() and always
returns number of LVs from user perspective.

2ba0dd20fb Introduce lv_set_visible & lv_set_invisible and use lv_is_visible always.
The vg->lv_count parameter now includes always number of visible
logical volumes.

Note that virtual snapshot volume (snapshotX) is never visible,
but it is stored in metadata with visible flag.

c4d4403955 Fixed bug where lvresize option -t was not properly passed to fsadm.
Using argv[] list in exec_cmd() to allow more params for external commands.
Fsadm does not allow checking mounted filesystem.
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
Fsadm improved handling of command line options.

7f4173ab22 Fail add tree node when requested major/minor is used.
Check for major/minor collision is added in _add_dev_to_dtree()
where we already read info by uuid,
so in the case of requesting major/minor it queries device-mapper
by major/minor for device availability.

6790656af6 Add lv_is_active() to determine whether an lv is active.
Handles non-clustered as well as clustered.  For clustered,
the best we can do is try exclusive local activation.  If this
succeeds, we know it is not active elsewhere in the cluster.
Otherwise, we assume it is active elsewhere.
